LOS ANGELES (AP) — Officials have vowed to find what sparked the inferno aboard the dive boat Conception that killed 34 people in waters off Southern California, but vital evidence may have gone down with the ship or drifted out to sea.The main piece of evidence, the charred remains of the boat, rests on the sea floor in 60 feet (18 meters) of water. Other items that could provide valuable clues could have been carried away by tides or destroyed in the blaze that burned so hot DNA is needed to identify the dead."All of that will be a very large hurdle to overcome," said George Zeitler, a former Coast Guard inspector who runs his own marine investigation firm. "It will definitely make for a complex investigation."Investigators will want to craft a timeline of the ship's final voyage from the moment it pulled away from a Santa Barbara dock early Saturday morning until dispatchers received the frantic mayday call of the breathless captain overwhelmed by smoke, experts said.RELATED: San Diego woman killed in deadly Conception boat fire off Santa BarbaraThey will look at the ship's layout and whether the bunk room below deck was too cramped and had enough exits, review maintenance records and even study photos and videos from people who have been on the boat to look for valuable evidence.As the investigation into the Labor Day tragedy expands on land and sea, federal and local authorities will look not only at determining what went wrong but also seek lessons that could lead to changes in commercial vessel regulations."Our mission here while we're on scene is to determine how this happened, why it happened and what safety improvements are needed to prevent it from ever happening again," said Jennifer Homendy of the National Transportation Safety Board.The fire, investigated with help from the FBI and Bureau of Alcohol, Tobacco, Firearms and Explosives, is being treated as an accident and there's nothing to suggest anything "nefarious," said Santa Barbara County Sheriff Lt. Erik Raney.The Conception, owned by Truth Aquatics, had been chartered for three days by a commercial dive outfit based in Santa Cruz to explore the rugged Channel Islands, sometimes referred to as the Galapagos of North America, about 20 miles (32 kilometers) south of Santa Barbara.The mayday call came at 3:15 a.m. Monday as passengers would have been sleeping while the boat was anchored just off Santa Cruz Island.While initial details were limited, Santa Barbara County Sheriff Bill Brown said fire above deck blocked the one stairway and an emergency exit hatch where 33 passengers and one crew member were sleeping in their bunks. It's not known if any alarm sounded or what the people below deck may have done to try to escape."If an emergency exit is blocked due to fire and prevents one from escaping, it's a horrific situation," said Hendrik Keijer, an investigator with Robson Forensic who has captained cruise ships and operated cargo boats. "Vessels are mazes."The five survivors were all crew members, including the captain. They apparently jumped from the boat's bow, where the stairway led to the sleeping quarters, and swam to the stern, where they escaped in a dinghy and were taken aboard a nearby boat.Attorney James Mercante, a former merchant marine officer who has defended thousands of maritime casualty cases, said it was unusual that only crew members survived, but that is likely because they were above deck.Mercante said he would want to find out what the crew did upon being alerted to fight the fire and for how long before they abandoned ship."Something was ignited that spread a fire rapidly," Mercante said. "It must have spread awfully quickly if nobody but the crew got out."Even with limited physical evidence, fire investigators should be able to pinpoint where the fire began, though finding the cause will be more difficult, Mercante said.The leading causes of boat fires are, specifically, electrical problems and, generally, stupidity, said Walter Godfrey, who has investigated more than 2,000 boat fires in a career spanning a half-century.By all accounts Godfrey has seen, Truth Aquatics had a good reputation and a clean record of service and was not the type of outfit to employ do-it-yourself electrical wiring."I don't think they'd be cutting those kind of corners," Godfrey said. "I would think just off the top of the head this would have to have been something totally accidental and not something ... you would anticipate."Coast Guard records show fire safety violations on the Conception in 2014 and 2016 were quickly fixed. There were no deficiencies found in February or August 2018 inspections.The same problems that lead to house fires every day can also sink ships: kitchen fires, unextinguished cigarette butts and gas leaks.While experts did not want to speculate on a cause, Godfrey said he would want to know more about the built-in barbecue on board and where gasoline was stored for the dinghy. He said electrical fires are most common because a boat — even when docked — is always moving and wires get chafed and exposed. They can arc and spark or ignite gas vapors.A fire on board can rapidly become a terrifying situation with no help nearby."It's very difficult to fight fires without outside help," Keijer said. "You're really on your own in most instances. It's up to the vessel's crew to fight fires. It's not like one can easily escape a vessel. You walk out of a building if a fire occurs on land. That's not as easy on vessels." 5515

LOS ANGELES (AP) — Authorities identified five additional victims Tuesday as divers searched for the last missing passenger who died in a fatal boat fire off the coast of California.As the families mourned, officials pursued a criminal investigation into the blaze that killed 34 people on Labor Day.Santa Barbara County Sheriff Bill Brown said the victims, 21 women and 13 men from 16 to 62 years old, appear to have died from smoke inhalation before they were burned. Five of six crew members, including the captain, survived after multiple efforts to rescue the dozens trapped below deck.Authorities said efforts to find the final victim and salvage the Conception are expected to continue Wednesday.The five additional victims, all from California, are Adrian Dahood-Fritz, 40, of Sacramento; Lisa Fiedler, 52, of Mill Valley; Kristina "Kristy" Finstad, 41, of Tamrick Pines; Fernisa Sison, 57, of Stockton, and Kristian Takvam, 34, of San Francisco.Finstad, a marine biologist who led the scuba tour, had led hundreds of dives in the Channel Islands. She had just returned from spending several years sailing across the Pacific with her husband.Fiedler, a Michigan native, was a hairdresser and photographer who thought of herself as "part fish" because of her ocean addiction.The other three victims identified Tuesday were on the boat with coworkers and loved ones.Sison's husband, Michael Quitasol, and her three stepdaughters also perished in the fire. Sison and Quitasol worked at St. Joseph's Medical Center in Stockton.Dahood-Fritz and her husband, professional photographer Andrew Fritz, also both died in the blaze. Dahood-Fritz had recently started a job as a senior environmental scientist for California's Ocean Protection Council under the California Natural Resources Agency.Takvam was a vice president of engineering at the education platform Brilliant in San Francisco. His coworker, Carrie McLaughlin, also died.Authorities were working to identify the last victims and release their remains to families.As part of the investigation, the FBI is seeking photos and videos related to the fire as multiple agencies examine whether the captain and boat owners followed safety requirements. 2215

LOS ANGELES (AP) — Deputies arrested a 13-year-old boy and seized a semi-automatic rifle after he threatened to shoot other students and staff at a Los Angeles-area middle school, authorities said Friday.In a separate case, a boy at another school was taken into custody involving a planned shooting.The arrests came barely a week after deputies were frantically summoned to a high school in Santa Clarita, where a 16-year-old boy killed two fellow students and took his own life.Since then, the Los Angeles County Sheriff’s Department has investigated at least 30 school threats, spokesman Sgt. Bob Boese said.RELATED: Santa Clarita high school shooting: 2 killed, 3 hurt; suspected shooter in 'grave' conditionThe incidents that resulted in the arrests were the only ones deemed credible.At Animo Mae Jemison Charter Middle School in Willowbrook, just south of downtown Los Angeles, multiple students overheard the 13-year-old say Thursday that he would carry out the shooting on campus the following day, Sheriff Alex Villanueva said.The students alerted teachers and police were notified.Deputies searched the boy’s home and discovered an AR-15-style rifle, 100 rounds of ammunition, a list of names and a drawing of the school, Villanueva said.The boy was arrested without incident on suspicion of making criminal threats. An adult male relative also was arrested and could face weapons charges, Boese said.RELATED: Teen used ‘ghost gun’ in California high school shootingInvestigators were trying to determine who owns the gun that authorities initially called a ghost gun — a weapon without a serial number made from parts from other guns. Villanueva later clarified the weapon has a serial number.Villanueva praised school officials for quickly notifying authorities about the threat.“The fact that people stepped forward and said what they had heard led us to prevent a tragedy today,” he said.The other boy was arrested Thursday in Palmdale, north of Los Angeles. Villanueva said the student at Knight High School made threats on social media following a campus fight.The sheriff said the boy acknowledged posting threats along with pictures of a teen with a gun. No weapon was recovered in the case.RELATED: Trauma Surgeons call for urgent intervention after school shootingThe sheriff’s department still hasn’t determined a motive for the deadly Nov. 14 shooting at Saugus High School in Santa Clarita.Villanueva said the . semi-automatic pistol used by gunman Nathaniel Berhow was assembled from gun parts and did not have a serial number. Police have not determined where and when Berhow got the gun.___Associated Press reporters Brian Melley and Michael R. Blood in Los Angeles contributed to this report. 2728

LOS ANGELES (AP) — A woman at Dodger Stadium was taken to a hospital Sunday for precautionary tests after being struck in the head by a foul ball from Los Angeles star Cody Bellinger during the first inning of a game against the Colorado Rockies.The young woman was sitting four rows from the field along the first base line, just beyond protective netting that extends to the end of the visiting dugout. She was hit by a sharp line drive by Bellinger, who checked on her between innings. She at first stayed in her seat and was given an ice pack, but she left about 15 minutes later for further attention.A first-aid person who treated the woman says she was taken to the hospital for precautionary tests but that she was alert and answering questions. The name of the woman was not released."It was weird. I saw it literally hit her face," Bellinger said. "I'm sure it was tough for everyone. I went over the next half inning to make sure. She said she was all right and gave me a thumb's up."Manager Dave Roberts came out to talk with Bellinger after the foul ball. Play was delayed for nearly six minutes as players watched the first-aid crew treat the woman.A woman died last August after being struck in the head by a foul ball at Dodger Stadium.All 30 major league stadiums expanded protective netting to at least the far ends of the dugouts at the start of the 2018 season after several fans were injured by foul balls two years ago.Fan safety has received further scrutiny after a young girl was struck by a foul ball in Houston during a game on May 29. The Chicago White Sox and Washington Nationals recently announced that they will extend their netting to the foul poles.Roberts said he would like to see it happen at other ballparks."I think that definitely talks like that need to intensify," he said. "For me, as we talk about getting ahead of things, I don't see anything wrong with that idea."Bellinger is also in favor of extending the netting."I would assume that would be a smart decision," he said. "The people in the front row don't have enough reaction time. I'm over at first base, and I have to be ready, and they're 10 feet over from me. That's a scary situation." 2198

LOS ANGELES (CNS) - Achieving a feat that a human being might even find difficult, a mountain lion successfully managed to cross the San Diego (405) Freeway in the Sepulveda Pass, National Park Service officials announced Thursday. Researchers believe the lion known as P-61 managed to traverse the freeway from west to east between 2 and 4 a.m. July 19. According to the NPS, another lion named P-18 was fatally struck by a vehicle in the same area of freeway while attempting a crossing in 2011, and another lion that was not being tracked by researchers was struck and killed in 2009. The only other lion known to have crossed the 405 Freeway is Griffith Park's famed resident lion P-22. That lion was not being tracked with a GPS collar at the time, so little is known about where and when he made the trek. Researchers say DNA testing shows P-22 was born in the Santa Monica Mountains, so he must have crossed both the 405 and 101 Freeways to have reached Griffith Park. ``Although P-61 successfully crossed the 405, his feat is a reminder of how challenging Southern California's road network is for mountain lions and other wildlife as well,'' said Jeff Sikich, a biologist with the Santa Monica Mountains National Recreation Area. ``Others haven't been so lucky.'' The issue of extensive development and freeways acting as physical barriers to migration have long been identified as threats to the continued survival of mountain lions in the area. At least one study has suggested that the lions will be extinct within 50 years due to the lack of breeding partners, leading to rampant inbreeding among the current population. P-61 now inhabits an area between the 405 and 101 Freeways, where researchers say at least one other lion resides. That lion is not outfitted with a GPS collar and has only been seen on surveillance footage in the area over the past five years. ``It will be interesting to see if P-61 stays in the area, whether he decides to challenge the uncollared lion or if he heads back to the other side of the freeway,'' Sikich said. ``Although it's a relatively small area of habitat, it's certainly larger than the Griffith Park area and does have a patchwork of natural areas.'' P-61 is believed to be about 4 years old. The lion was first captured and fitted with a GPS collar in October 2017. 2330
